dreamy trip (GP4/5/MIDI) C4C

i havent posted a song in a while. ive been listening to a lot of the doors, floyd, the beatles, the zombies etc. lately. this song is definitely trippy. im not sure what key its in, its either minor or modulates between keys. im very content with what i have so far, its unlike anything ive ever written. any suggestions would be greatly appreciated and C4C of course!

edit: Ive added keys. pretty basic. can anyone help me create some better key parts? i like the chords in the chorus, idk about the timbre of the violins. suggestions? i want the keys to be driving, not too noticeable, but creates the steady pace.
